Composite brush

Patented Mar. 16, 1954 UNITED STATES PATENT OFFICE This invention is a composite brush having two brushing surfaces positioned in different planes, particularly for use in cleaning the corners of a room, including the base boards.

The principal object of the invention is to provide a double-faced brush where one of the brushes is angularly positioned with respect to the other so that the brush may be used for slmultaneously cleaning two surfaces that are angularly positioned with respect to each other.

In some rooms, especially hospital rooms, the base boards, instead of being vertical, have their lower edges projecting farther into the room than the upper edges, so that the base board slants downwardly into the room. The angle formed between such base boards and the floor is an obtuse angle, making an obtuse corner which is somewhat easier to clean than the usual rightangled corner.

Another important object of the invention is to provide a two part brush, where one of the brushes is angularly positionable with respect to the other, so that the brush will fit into room corners where the angle between the base board and the floor is an obtuse angle, so that both faces of the brush operate simultaneously to clean this-type of room corner.

Further features of the invention will be described in connection with the accompanying drawings, wherein:

Fig. l is a perspective view of my composite brush.

Fig. 2 is a plan view of the brush of Fig. 1 on a smaller scale.

Fig. 3 is an end view of the brush of Fig. 2.

Figs. 4, 5 and 6 are side views of the brush in different operative positions.

Fig. 7 shows a modification.

Referring now to these figures, one of the brushes, such as the floor brush, comprises the usual brush back 2 which may be of wood, plastic or the like, containing bristles 4 anchored to the base in the usual way. The bristles 4 terminate in a plane indicated by the line 6 which plane would be horizontal when the brush is used in the lower corner of a room.

The second brush I comprises a usual back 8 of wood, plastic or the like, having bristles I0 terminating in a plane indicated generally by the line II.

The two brushes are combined into a unitary article for simultaneous use, by a bracket indicated generally at I2, which bracket comprises a plate I4 secured to the back of brush 2 by screws I6.

2 Claims. (01. 15-106) The bracket also comprises a plate I8 at right angles to the main plate I4. Extending outwardly as shown in Fig. l, and at right angles to both the plates I4 and I8, is a third plate 20 secured both to plate I4 and to plate I8, along the line 22.

In order to secure the brush I to the plate 20 and to provide for positioning the back 8 at various angles, base 8 is provided with a flared passageway 24 through which passes the headed bolt 26, the threaded outer end 28 of the bolt passing through a slot 30 in plate 20. The bolt is drawn home to locking position by a wing nut 32.

Where the composite brush is to be used in a room having the usual right-angled corner, the two brushes would be positioned as shown in Fig. 4, where the two brush surfaces are approximately at right angles to each other.

Where the base board of the room forms an obtuse angle with the floor, as indicated by the are 34 in Fig. 5, a wedge 36, slotted at 37 to a straddle the bolt 26, is inserted in the proper position between plate 20 and the brush back 8, as shown in Fig. 5, and the wing nut 32 tightened up, thereby positioning the brush I0 at the proper angle so that both the floor and the base board in the corner are efiectively cleaned in one operation.

' Fig. 6 shows a. thinner wedge 38a for obtaining a different angular setting for brush I.

Where the floor and walls merge into one another and form a concave corner, the brush surface would terminate in a convex curve II, to fit such concave corner, as in Fig. 7

An operating handle of any desired type may be used with the brush such, for example, as the handle 40, of any convenient length, to which is secured the angled connecting bar 42, which is clamped to the plate I4 of the bracket I2 by a bolt 44 anchored in the base of the brush. and cooperating wing nut 46.

Lock washers of any desired type may be used with the wing nuts 32 and 46 to avoid loosening of such nuts. 1

While the invention has been described in some detail, it should be understood that the invention is not to be limited to the precise details shown, but may be carried out in other ways. While the preferred use of the composite brush is for cleaning corners of a room having slanted base boards, it should be understood that the brush may be used in any situation to which it is particularly adapted.

I claim as my invention:

1. A composite brush of the character described, comprising a pair of brushes, a common mounting bracket for said brushes, said mounting bracket including two angularly positioned plates, located in different planes, and adapted to engage respectively with the backs of the brushes, for thereby positioning the brushes for simultaneous operation in different planes, means for holding one of the brushes in clamping engagement with its carrying plate, means for pcsitioning and holding the other brush in various angular positions with respect to its carrying plate, comprising a wedge adapted to be --posiv tioned between the back of said other brush and its carrying plate, and means for holding said other brush, its carrying plate, and said wedge in clamping engagement.

2. A composite brush for cleaning the baseboards of the room and the floor adjacent the baseboards, comprising a pair of brushes, a mounting bracket comprising angularly positioned plates secured respectively to the backs 4 of the brushes, and means for positioning the holding one of the brushes in different angular positions comprising a wedge adapted to be positioned between the brush and its carrying plate, and means for holding the brush, its carrying plate and the element in clamping engagement.
